How do you calculate the total infusion time in hours if 1200 mL is to be administered at 80 mL/hour?

To calculate the total infusion time when administering 1200 mL at a rate of 80 mL/hour, you use the formula:

Total infusion time (hours) = Total volume (mL) / Flow rate (mL/hour).

Applying the values, you would divide the total volume of 1200 mL by the flow rate of 80 mL/hour:

1200 mL ÷ 80 mL/hour = 15 hours.

This calculation shows that it will take 15 hours to infuse the entire 1200 mL at the specified rate. Understanding how to apply this formula is essential in medication administration to ensure accurate dosing and patient safety.
